Specification of Letters Patent.

Patented Nov. 28, lltl llfi.

Application filed April 17, 1915. Serial No. 21,951.

To all whom it may concern:

Be it known that we, ANDREW PAUL and JOHN A. SMITH, citizens of theUnited States, residing in the city and county of Philadelphia and Stateof Pennsylvania, have invented certain new and useful Improvements inFoldable Stands, of which the following is a specification.

Our invention relates to improvements in foldable stands employing acentral post, legs pivoted to the post, a collar slidable on the post,braces connecting the legs and the collar and means to hold the collarin position upon the post when the stand is in use.

The object of our invention is to provide a novel, simple, inexpensiveand efficient means to hold the collar in position upon the post whenthe stand is in use and to permit the stand to be readily folded andunfolded as desired.

With this object in view, our invented stand consists of the elementsand combinations of them hereinafter fully described and particularlyclaimed.

In the accompanying drawings, illustrating our invention, Figure 1 is afront elevation of a foldable stand embodying our invention. Fig. 2 is avertical section, on line 22 of Fig. 1. Fig. 3- is a horizontal section,on line 33 of Fig. 2.

Referring to the drawings, 4 designates a central post provided with abracket 5 which is secured on the lower end thereof. The bracket 5 isprovided with outwardly-extending lugs to which are pivoted the upperends of downwardly and outwardly diverging legs 6. Slidable verticallyupon the post 4, above the bracket 5, is a collar 7 provided withoutwardly-extending lugs which have the upper ends of braces 8 pivotedthereto as shown. The lower ends of the braces 8 are pivoted to the legs6, and the parts thus far described are related to each other so that byraising the collar 7 from the position shown upon the post 4, the legs 6and braces 8 will be raised and folded inwardly adjacent to the post 4,and that by then lowering the collar 7 to the position shown, the legs 6and braces 8 will be unfolded into the condition shown, in the usualmanner common to well known music and other stands.

The bracket 5 is provided with a lug or arm 9 which extends upwardlytherefrom adjacent to the post 4 and has its upper end bifurcated forthe reception of the lower portion of a latch arm 10 which is pivoted at11, to the lug 9. The upper portion of the latch arm 10 is forcedoutwardly by the action of a coiled spring 12 which is housed within anopening or socket formed in an'enlarged portion 13 of the arm 10 andbearing against the arm 10 and the post 1, the wall of the socketsurrounding the spring 12 and holding it in place. Outward movement ofthe upper portion of the latch arm 10 is limited by the lower portion14-v thereof engaging the post 4.

When the parts are in the position shown in the drawings, the upper endportion of the latch arm 10 extends through and above an opening 15which extends longitudinally through the collar 7 outwardly of the post1; and the arm 10 is provided with a tooth or projection 16 whichextends outwardly above the collar 7 and is adapted to engage the. topthereof and prevent upward move ment of the collar upon the post 4.Downward movement of the collar 7 is prevented by the enlarged portion13 of the arm 1.0 the portion 13 extending outwardly and forming a stopspaced from the tooth or projection 16 a distance equal or substantiallyequal to the length of the collar 7, so that when the parts are in theposition shown, the collar 7 will be held by and between the parts 16and 13 against either up or down vertical displacement upon the post 4:.

When it is desired to raise the collar 7 upon the post 4 to raise thelegs 6 and braces 8 and fold them inwardly, the upper end of the latcharm 10 is pressed by hand toward the post 4 until the bottom of theprojection 16 is disengaged from the top of the collar 7, thus releasingthe collar and permitting it to slide upwardly upon the post for thefolding operation. After the collar 7 has been raised above the latcharm 10, the latch arm is moved back to the position shown by the spring12 and the upper beveled end 17 of the latch arm 10 is directly beneaththe outer wall 18 of the longitudinal opening 15 in the collar 7, sothat when the collar 7 is again moved clownwardly upon the post 41, thewall 18 will engage the beveled end 17 of the arm 10 and force itinwardly and cause it to enter the opening 15, and, after the collar 7is moved down against the stop 13, the spring 12 will force the upperend of the latch arm 10 outwardly, moving the tooth or projection 16nection with foldable stands of any character, we have illustrated it inthe drawings as applied to a music stand whereof the post 4 forms thelower section of atelescopic standard 19 which supports a foldable musicrack 20 at its upper end.

We claim:

1. In a foldable stand, the combination of a central post, legs pivotedto parts fixed to the lower end of said post, a collar slidable on saidpost and having a longitudinal opening extending therethrough outwardlyof said post, braces connecting said legs and said collar and pivotedthereto, and a latch arm connected to a part fixed on said post betweenthe lower end thereof and said collar and having a free end extendingupwardly and adapted to pass through said opening in said collar, theupper end of said latch arm having an outwardly extending projectionadapted to engage over the top of said collar and prevent its upwardmovement upon said post.

2. In a foldable stand, the combination of a central post, legs pivotedto parts fixed to the lower end of said post, a collar slidable on saidpost and having a 1011- gitudinal opening extending therethroughoutwardly of said post, braces connecting said legs and said collar andpivoted thereto, a latch arm pivoted to a part fixed on said postbetween the lower end thereof and I said collar and having a free endextending upwardly and adapted to pass through said opening in saidcollar when said collar is moved longitudinally, and a spring tending toforce the upper end of said arm out wardly from said post, the lower endof said arm being adapted to engage said post and limit the outwardmovement of the upper end thereof and prevent it from being moved out ofalinement with the opening in said collar, the upper end of said latcharm having an outwardly extending projection adapted to engage over thetop of said collar and prevent its upward movement upon said post. 4

3. In a foldable stand, the combination of a central post, legs pivotedto parts fixed to the lower end of said post, a collar slidable on saidpost, braces connecting said legs and said collar and pivoted thereto, alatch arm pivoted to a part fixed on said post and provided with anoutwardly extending hollow stop projection adapted to engage said collarand limit the movement thereof, and a spring housed within saidprojection and interposed between said latch arm and said post andtending to force said latch arm outwardly, the upper end of said latcharm having an outwardly extending projection adapted to engage saidcollar and prevent its upward movement upon said post.

In testimony whereof we afiix our signatures hereto.
